ITH Outlines Large Geophysical Anomalies Associated With High Copper-Gold-Silver Mineralization on BMP Project, Alaska

VANCOUVER, BRITISH COLUMBIA--(Marketwire - May 13, 2008) - International Tower Hill Mines Ltd. ("ITH" or the "Company") (TSX VENTURE:ITH)(AMEX:THM)(FRANKFURT:IW9) is pleased to announce the results from a recent high resolution airborne magnetic and EM survey completed over key mineralized areas of the Company's BMP project, Alaska. In the spring of 2008, Fugro, the Company's contractor, completed an airborne magnetic and electromagnetic survey of the core target area covering an area of 30 square kilometres in two blocks with a nominal line spacing of 50 metres. The results have outlined several large geophysical anomalies spatially associated with the outcropping polymetallic (copper-gold-silver) skarn deposits that were discovered in 2007 (to see Figure 1 please click on: http://media3.marketwire.com/docs/ith513a.jpg).

The largest anomaly is associated with the 6120 target area and covers approximately 1 square kilometre forming at an important structural intersection on the south side of the core intrusive. Twenty rock samples collected from a 150 metre diameter area of outcropping skarn at the 6120 target averaged 2.3% copper, 3.4 g/t gold, 33 g/t silver, 0.16% nickel and 0.07% cobalt (to see Figure 2 please click on: http://media3.marketwire.com/docs/ith513b.jpg). In addition, similar skarn type mineralization was found 2 kilometres to the north at the 6920 prospect.

The Dall and Little Bird prospects, located on the northern target block (approximately 5 kilometres north), also appear to be associated with skarn and distal skarn type mineral systems. The Dall target was drilled by Anaconda Mining Company in the 1980's with two diamond drill holes, each of which intersected very significant high-grade mineralization (4.0% copper, 11.8 oz (370 g/t) silver, 1.0% zinc and 0.3% lead over a true thickness of 3.5 metres and 0.9% copper, 6.0% zinc, 5.7oz (177 g/t) silver and 1.0% lead over a true thickness of 5.5 metres). The size and dynamic range of the anomalies suggest that they are related to a large base and precious metal bearing hydrothermal system which warrants aggressive follow-up exploration.

BMP Project Summary

The BMP property is located approximately 40 kilometres north of the Company's Terra project. The property covers approximately 13,193 hectares and is comprised of 108 Alaska State mining claims staked in October 2006 and owned 100% by the Company (approximately 6,993 hectares) and approximately 6,200 hectares of fee simple lands held under the exploration agreement with option to lease from Cook Inlet Region, Inc. (an Alaska Native Corporation) (See NR08-07).

The property is underlain by Paleozoic sediments which have been intruded by dikes and plugs of early Tertiary age. Exploration by the Company in 2007 confirmed a number of mineralized zones with numerous high-grade copper, silver, zinc and gold values being returned. This work linked much of the mineralization to a prolific skarn-type mineralizing environment and highlighted the potential of the belt. At the 6120 and 6920 prospects calcareous horizons have been extensively replaced by skarn mineralization, including massive pyrrhotite with chalcopyrite and sphalerite. High gold values are present at both of these prospects with grades of several grams in specific samples. Both prospects occur on the flank of a Tertiary intrusive body. The focus of the Company's 2008 BMP program is to define drill targets to test the size and continuity of these large skarn systems.
